質問 # 27
Export and import a Kubernetes application (YAML export)
Task Information : Export typical app objects from orders and apply them into a new namespace orders- copy.
正解:
解説:
See the solution below in Explanation:
Explanation:
* Export objects to YAML
* oc -n orders get deploy,svc,route,cm,secret -o yaml > orders-app.yaml
* Exports key application resources.
* Create target namespace
* oc new-project orders-copy
* Apply exported YAML
* oc -n orders-copy apply -f orders-app.yaml
* Recreates resources (some fields may need adjustment, like namespaces or immutable fields).
* Validate
* oc -n orders-copy get all

Kubeconfig Management - Approve CSR
正解:
解説:
See the solution below in Explanation:
Explanation:
Step 1: Identify the pending certificate signing request.
The lab names it audit-csr.
Step 2: Run the approval command:
oc adm certificate approve audit-csr
Step 3: Confirm approval.
The lab output shows:
certificatesigningrequest.certificates.k8s.io/audit-csr approved
Detailed explanation:
In Kubernetes and OpenShift, a CSR must be approved before the requester can use the signed certificate for authentication. This Task approves the CSR named audit-csr, which is likely associated with the audit user or service account access flow in the lab. Certificate-based authentication is commonly used for kubeconfig access because it enables secure client identity without relying solely on tokens. Until the CSR is approved, the certificate cannot be trusted by the cluster API for authenticated operations. Administrative approval is therefore a gatekeeping step that ensures only intended certificate requests become valid credentials. This Task is part of a broader kubeconfig workflow that continues with setting credentials and defining context.
質問 # 29
Configure BackupStorageLocation and VolumeSnapshotLocation
Task Information : Configure OADP/Velero storage locations and confirm they show as Available.
正解:
解説:
See the solution below in Explanation:
Explanation:
* Create a secret for cloud credentials (S3-compatible example)
* oc -n openshift-adp create secret generic cloud-credentials \
* --from-file=cloud=/path/to/credentials
* Velero uses this secret to authenticate to object storage.
* Create/Update the DataProtectionApplication (DPA)
* Apply a DPA CR that defines:
* backupLocations (bucket, endpoint URL, region, etc.)
* snapshotLocations (if using snapshots)
* Verify BackupStorageLocation and SnapshotLocation
* velero backup-location get
* velero snapshot-location get
* Status should be Available, meaning storage config is valid.

質問 # 30
Deploy Event Router and capture Kubernetes events in logging
Task Information : Deploy an event router so Kubernetes events are recorded as logs, then trigger events and confirm they appear in logging queries.
正解:
解説:
See the solution below in Explanation:
* Deploy event router resources
* Apply a deployment/serviceaccount/rolebinding manifest for eventrouter:
* oc apply -f eventrouter.yaml -n openshift-logging
* Eventrouter watches event API and writes them to stdout (collected by logging).
* Verify eventrouter pod is running
* oc -n openshift-logging get pods | grep -i event
* Trigger some events
* oc -n default run evtest --image=busybox --restart=Never -- sleep 1
* oc -n default delete pod evtest
* Creation/deletion generates events.
* Query logs for events
* In the logging UI/backend, search for the namespace/pod name evtest or eventrouter messages.
* Explanation: Validates that events are being converted to searchable logs.
質問 # 31
Create a full application backup (resources + PV data)
Task Information : Create a Velero backup of namespace orders including PV snapshots.
正解:
解説:
See the solution below in Explanation:
Explanation:
* Confirm resources and PVCs exist
* oc -n orders get all
* oc -n orders get pvc
* Ensures there is something meaningful to back up.
* Create backup including volume snapshots
* velero backup create orders-full --include-namespaces orders --snapshot-volumes
* Captures Kubernetes objects and requests PV snapshots where supported.
* Check status/details
* velero backup describe orders-full --details
* velero backup logs orders-full
* Review warnings/errors and confirm snapshot actions.
